Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal degreasing devices, specifically a centrifugal degreasing device for metal surface treatment. Background Technology

[0002] Centrifugal degreasing equipment for metal surface treatment is commonly known as a centrifugal degreasing machine. It is a special device that uses centrifugal force to separate metal shavings from oil stains. The centrifugal force generated by high-speed rotation separates the metal shavings from the attached oil stains. The metal shavings are thrown against the inner wall of the equipment under the action of centrifugal force, while the oil stains are separated and discharged due to density differences, thus achieving efficient degreasing.

[0003] During degreasing, the material bucket is placed inside the degreasing machine. The degreasing machine usually uses springs to compress the material. However, with long-term use, the springs are prone to fatigue failure and uneven compression, causing the material bucket to shift, reducing the degreasing efficiency, and leaving liquid residue on some metal surfaces, which affects the degreasing effect. Therefore, it is necessary to provide a method that can firmly fix the material bucket inside the degreasing machine to improve the degreasing effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a centrifugal degreasing device for metal surface treatment, comprising:

[0028] The oil extractor 11, the rotating drum 12, and the material hopper 14 are arranged inside the oil extractor 11 and the material hopper 14 is placed inside the rotating drum 12.

[0029] The adjustment assembly includes a connecting cover 21, a circular groove 22, a fixing bracket 23, a threaded hole 24, a threaded rod 26, and a pressure cap 27. The connecting cover 21 is hinged to one side of the rotating barrel 12. The circular groove 22 is opened in the center of the connecting cover 21. The fixing bracket 23 is fixed to the upper surface of the connecting cover 21. The threaded hole 24 is opened in the center of the upper surface of the fixing bracket 23. The threaded rod 26 is threaded through the threaded hole 24. The pressure cap 27 is rotatably installed on the lower end of the threaded rod 26.

[0030] The lower end of the threaded rod 26 is connected to a bearing, and the lower surface of the bearing is fixed to the upper surface of the pressure cap 27. When the threaded rod 26 rotates, the pressure cap 27 will move vertically up and down. The entire outer shell of the oil separator 11 is used to protect the internal rotating parts and prevent operators from contacting the dangerous area of ​​high-speed rotation. The rotating drum 12 generates centrifugal force through high-speed rotation, which throws the metal shavings or liquid in the material drum 14 toward the drum wall to achieve solid-liquid separation. The fixing frame 23 provides structural stability and prevents the threaded rod 26 from shaking when rotating. The threaded hole 24 converts the rotational motion into vertical linear motion through threaded engagement, driving the pressure cap 27 to press down.

[0031] The outer surface of the oil extractor 11 is hinged with a protective cover 13. The fixed frame 23 and the inner wall of the circular groove 22 are provided with limit grooves 25. Limit blocks 29 are fixed on both sides of the pressure cover 27. The limit blocks 29 are slidably placed in the limit grooves 25. An oil hole 28 is fixed in the center of the pressure cover 27. The oil hole 28 corresponds to the opening of the material bucket 14.

[0032] The pressure cap 27 is used to press the upper surface of the material barrel 14 to prevent metal chips from being thrown out during rotation. The limiting groove 25 provides a guide for the limiting block 29 of the pressure cap 27. The limiting block 29 is slidably placed in the limiting groove 25 to prevent the pressure cap from rotating or shifting laterally.

[0033] Working principle:

[0034] When degreasing, simply place the metal shavings-filled bucket 14 inside the rotating bucket 12, then close the connecting cover 21 through the hinge, and rotate the threaded rod 26 so that the threaded rod 26 moves vertically up and down inside the threaded hole 24. The vertical movement of the threaded rod 26 drives the pressure cover 27 to move vertically, so that the pressure cover 27 presses tightly against the upper surface of the bucket 14.

[0035] This step, through the design of driving the pressure cap 27 to press the material barrel 14 by the threaded rod 26, solves the problems of fatigue failure, uneven pressing and poor adaptability in the traditional spring pressing method, and has the advantages of flexible operation, simple maintenance and high safety.

[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The locking assembly includes a locking block 31, a locking groove 32, a connecting hole 33, a connecting block 34, and a fixing groove 35. The locking block 31 is fixed to one side of the rotating barrel 12. The locking groove 32 is opened at the upper center of the locking block 31. The connecting hole 33 is opened on both sides of the upper end of the locking block 31, and the locking groove 32 and the connecting hole 33 are interconnected. The connecting block 34 is fixed to one side of the connecting cover 21. The fixing groove 35 is opened on one side of the connecting block 34, and the fixing groove 35 corresponds to the connecting hole 33.

[0038] The locking block 31 serves as the basic support structure for the locking assembly. The locking groove 32 is used to accommodate the connecting block 34 for initial positioning. The connecting hole 33 is used to install the movable column 38. The fixing groove 35 is used to accommodate the end of the movable column 38 for final locking.

[0039] Side brackets 36 are fixed on both sides of the locking block 31. Mounting holes 37 are opened on both sides of the side brackets 36. Movable columns 38 are slidably installed inside the mounting holes 37. The ends of the movable columns 38 extend into the connecting holes 33 and the fixing grooves 35. Two baffles 39 are fixed on the outer surface of the movable columns 38. One baffle 39 is fixed in the middle and the other baffle 39 is fixed at the end. A spring 391 is fixed on one side of the middle baffle 39.

[0040] The side bracket 36 serves as the mounting bracket for the movable column 38. The mounting hole 37 restricts the sliding range of the movable column 38, ensuring that it moves in a predetermined direction. The mounting hole 37 serves as a guide channel for the movable column 38, which is used to lock and unlock the connecting cover 21.

[0041] Working principle:

[0042] When opening the connecting cover 21, simply pull the two movable columns 38 to the sides. The movable columns 38 drive the baffle 39 to move outward. The outward movement of the baffle 39 compresses the spring 391, causing the end of the movable column 38 to exit from the fixed groove 35, allowing the connecting cover 21 to be opened directly. When the connecting cover 21 needs to be locked, under the elastic force of the spring 391, the spring 391 pushes the baffle 39 to move inward, causing the movable column 38 to move inward, so that the end of the movable column 38 extends into the fixed groove 35, locking the connecting cover 21.

[0043] This step, through the linkage design of the movable column 38, the baffle 39 and the spring 391, enables the quick unlocking and reliable locking of the connecting cover 21, which can effectively improve production efficiency and reduce safety hazards.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
